They strip for Allure magazine...

Keri Hilson, Ashley Tisdale and Big Bang Theory star Kaley Cuoco have all posed naked for a new magazine shoot.

The girls all took the brave move for the Allure magazines annual Body Issue with Ashley taking the opportunity to show her more mature side, away from the High School Musical bubble.

Speaking about the shoot, 25 year old Ashley said: "I'm not just the young girl everybody thinks I am. I'm actually a woman."

Keri meanwhile saw the shoot as a chance to embrace her insecurities, saying:

"We (women) do a lot of things to seek validation: I have to get more expensive handbags or fake lashes or fake boobs. This shoot was about dropping all that. It’s so empowering to embrace my insecurities."
